| 1. डाइनामिक मेमोरी आवंटन क्या है? |  |
उत्तर: डाइनामिक मेमोरी आवंटन के द्वारा, C भाषा में हम कंप्यूटर के रनटाइम मेमोरी इत्यादि की आवश्यकता के अनुसार मेमोरी का उपयोग कर सकते हैं। इसमें, हम प्रोग्राम के चलते समय पर आवश्यक मेमोरी को आवंटित करते हैं और उसे प्रोग्राम के चलते समय वापस भी कर सकते हैं।
| 2. डाइनामिक मेमोरी आवंटन के लिए कौन सी C भाषा में उपयोग होती है? | |
उत्तर: डाइनामिक मेमोरी आवंटन के लिए C भाषा में malloc(), calloc() और realloc() जैसी फ़ंक्शनें उपयोग होती हैं।
| 3. malloc() और calloc() में क्या अंतर है? | |
उत्तर: malloc() फ़ंक्शन का उपयोग करके हम स्पष्ट रूप से निर्धारित मात्रा की मेमोरी आवंटित करते हैं, वहीं calloc() फ़ंक्शन का उपयोग करके हम 0 के साथ निर्धारित मात्रा की मेमोरी आवंटित करते हैं।
| 4. realloc() फ़ंक्शन का उपयोग क्यों किया जाता है? | |
उत्तर: realloc() फ़ंक्शन का उपयोग हमेशा वहीं किया जाता है जब हमें पहले से आवंटित की गई मेमोरी के आकार में परिवर्तन करने की आवश्यकता होती है। इसके द्वारा, हम मेमोरी का आकार बदल सकते हैं और पहले से आवंटित की गई मेमोरी की सीमा को बढ़ा सकते हैं या कम कर सकते हैं।
| 5. डाइनामिक मेमोरी आवंटन के लिए डीलीट करने के लिए कौन सा फ़ंक्शन उपयोग किया जाता है? | |
उत्तर: डाइनामिक मेमोरी आवंटन के लिए free() फ़ंक्शन का उपयोग किया जाता है। इस फ़ंक्शन के द्वारा, हम पहले से आवंटित की गई मेमोरी को प्रयोग न करते हुए उसे रिलीज़ कर सकते हैं।
